焊接車間除塵器設備，也叫集中式焊接煙塵凈化器。在車間內鋪設管道，每個焊接源都設有吸氣臂或集氣罩，方便進行源頭吸塵。

吸氣臂捕捉方式

Aspiration arm capture method

在吸氣罩的位置上設計了獨特的旋轉機構，保證了吸氣罩能夠通過任意方位對準焊接位置。吸氣罩通過流體設計和氣流模擬，使吸氣臂能夠最大量和最大范圍的捕捉焊接過程中產生的煙塵。

A unique rotating mechanism has been designed in the position of the suction hood, ensuring that the suction hood can be aligned with the welding position in any direction. The suction hood utilizes fluid design and airflow simulation to enable the suction arm to capture the maximum amount and range of smoke and dust generated during the welding process.

適用范圍：

Applicable scope:

吸氣臂的吸風罩尺寸為φ150-170，適合處理焊縫長度不超過100mm的焊接，工人焊接位置固定的情況。焊接方法適合手工電弧焊CO2氣體保護焊MAG焊MIG焊。

The size of the suction hood of the suction arm is φ 150-170, suitable for welding seams with a length not exceeding 100mm, and for situations where the worker's welding position is fixed. The welding method is suitable for manual arc welding, CO2 gas shielded welding, MAG welding, and MIG welding.

頂吸罩

Top suction hood

頂吸罩為了能夠捕捉在一個工位上產生的任意粉塵，其尺寸為設計成覆蓋工件所有的焊接位置，頂吸罩的外形為四凌臺形，每一面與地面的夾角不小于45°，為了避免橫向氣流的干擾，通常會在吸氣罩的側邊掛擋弧簾。

In order to capture any dust generated at a workstation, the size of the top suction hood is designed to cover all welding positions of the workpiece. The shape of the top suction hood is a four sided platform shape, with each side at an angle of no less than 45 ° to the ground. To avoid interference from lateral airflow, a blocking arc curtain is usually hung on the side of the suction hood.

頂吸氣罩適用于焊接位置固定，焊接位置較多的情況，工人可以在吸氣罩覆蓋的范圍內自由的焊接，產生的焊接煙塵都能夠順利的捕捉，達到很高的捕捉效率。

The top suction hood is suitable for situations where the welding position is fixed and there are many welding positions. Workers can freely weld within the range covered by the suction hood, and the welding smoke and dust generated can be captured smoothly, achieving high capture efficiency.

頂吸板

Top suction plate

頂吸板的捕捉原理類似于頂吸罩，兩者的區(qū)別在于，頂吸板為單層結構，采用了氣流模擬軟件詳細的模擬了其氣流組織過程，采用圓形吸口的結構，改頂吸罩的雙層結構為單層結構，有效的減少了頂吸罩的重量，減低了頂吸罩的壓力損失，同時頂吸板的外形也遠超頂吸罩。

The capture principle of the top suction plate is similar to that of the top suction cover. The difference between the two is that the top suction plate is a single-layer structure, which uses airflow simulation software to simulate its airflow organization process in detail. The circular suction mouth structure is adopted, and the double-layer structure of the top suction cover is changed to a single-layer structure, effectively reducing the weight of the top suction cover and reducing the pressure loss of the top suction cover. At the same time, the shape of the top suction plate is also much larger than the top suction cover.

焊接車間除塵器工作原理

Working principle of dust collector in welding workshop

焊接車間除塵器的凈化作用主要是依靠電暈極和沉淀極兩個系統(tǒng)來完成。當含塵氣體進入進氣喇叭口時，含塵氣體受到氣流分布板以及導流板的調整后，使氣流能較均勻地進入電場。在橫斷面不斷擴大的作用下，氣流速度迅速降低，其中一些較重的粗顆粒粉塵便失去速度而沉降下來。進入電場的含塵氣流由于電暈極通入高壓直流電，在陰極和陽極間形成一個相對穩(wěn)定的高壓電場，并在電暈極(本設備是陰極)附近產生電暈現(xiàn)象(放電)，使進入電場的含塵氣體被電離。電離后的氣體中存在大量的電子和正負離子，這些電子和離子與進入電場的塵粒相結合，使塵粒帶電。帶電塵粒在電場力的作用下趨向本設備陽極(正極板)和陰極(負極)，附著在陽極上的塵粒釋放出電子或負電荷，附著在陰極上的塵粒釋放出正電荷后，分別沉積在正負電極上。當粉塵沉淀到一定厚度，通過陰陽極振打系統(tǒng)的振打，將沉積的粉塵振落，進入集灰斗，通過排灰裝置放出，回收有用物料，被凈化的氣體排入大氣。

The purification function of the welding workshop dust collector mainly relies on two systems: corona electrode and precipitation electrode. When dusty gas enters the intake horn, it is adjusted by the airflow distribution plate and guide plate to allow the airflow to enter the electric field more evenly. Under the continuous expansion of the cross-section, the airflow velocity rapidly decreases, and some heavier coarse dust particles lose their velocity and settle down. The dusty airflow entering the electric field forms a relatively stable high-voltage electric field between the cathode and anode due to the high-voltage direct current passing through the corona electrode, and generates corona phenomenon (discharge) near the corona electrode (this equipment is the cathode), causing the dusty gas entering the electric field to be ionized. There are a large number of electrons and positive and negative ions in the ionized gas, which combine with the dust particles entering the electric field, making the dust particles charged. Under the action of electric field force, charged dust particles tend towards the anode (positive electrode plate) and cathode (negative electrode) of this equipment. Dust particles attached to the anode release electrons or negative charges, while dust particles attached to the cathode release positive charges and deposit on the positive and negative electrodes respectively. When the dust settles to a certain thickness, it is vibrated by the anode and cathode vibration system to settle the dust and enter the ash collection hopper. It is discharged through the ash discharge device to recover useful materials, and the purified gas is discharged into the atmosphere.
